Except if such evidence suggests/shows/proves that world's brains are mutating to be less intelligent, right? Man, you confuse the heck outta me...
It's just one piece of a very complicated puzzle. It must get ripped apart in order to get stronger. Remember, it is not the data we are arguing, or even the evidence, but the application of those that we are looking at. In fact, I think the terms data or findings might be better than evidence in this context. Otherwise, it could get confusing.
So let me take another real world example as I try to explain how we are not denying data, but questioning conclusions:
You work in public housing. I think I'm probably correct in saying that most in public housing do not have college degrees. Not all, of course, but most. Now I could look at that and say, see public housing and other social programs makes people dumb and makes them lack initiative. Certainly, some do make that conclusion. But is it correct? The data doesn't change, but we are looking for causation. Is it the public housing, or is public housing simply a symptom of a much bigger cause? I think the latter is correct, but to go into those causes here would take us way off topic.
We are not denying the findings, although we would like to see some collaberation. So we are withholding on that. We are not denying any conclusions, but we are offering other possible conclusions. And only by looking at ALL of the possiblities will we have better answers.
Char: Regarding the us and them comment. It seems everyone here is being pretty respectful and trying to understand each other. Can you set it aside for a while?
